Be particularly alert and cautious when
wearing hearing protection because
your ability to hear warnings (shouts,
alarms, etc.) is restricted.
THE CHAIN SAW
For illustrations and definitions of the
chain saw parts see the chapter on
"Main Parts."
WARNING
Never modify this chain saw in any way.
Only attachments supplied by STIHL or
expressly approved by STIHL for use
with the specific STIHL model are
authorized. Although certain
unauthorized attachments are useable
with STIHL chain saws, their use may, in
fact, be extremely dangerous.
WARNING
Never operate your chain saw if it is
damaged, improperly adjusted or
maintained, or not completely or
securely assembled.
If this chain saw is subjected to
unusually high loads for which it was not
designed (e.g. heavy impact or a fall),
always check that it is in good condition
before continuing work. Check in
particular that the fuel system is tight (no
leaks) and that the controls and safety
devices are working properly. Do not
continue operating this chain saw if it is
damaged. In case of doubt, have it
checked by your STIHL servicing dealer.
THE USE OF THE CHAIN SAW
Transporting the Chain Saw
WARNING
Always stop the engine before putting
the chain saw down. Carrying a chain
saw with the engine running may be
extremely dangerous.
Accidental acceleration of the engine
can cause the saw chain to rotate.
Always engage the chain brake when
taking more than a few steps.
By hand: When transporting your chain
saw by hand, the engine must be shut
off and the chain saw must be in the
proper position, i.e., grip the top handle
and place the muffler away from the
body; the chain guard (scabbard) should
be over the saw chain and guide bar,
which should point backwards, away
from the direction in which you are
walking.
By vehicle: When transporting in a
vehicle, keep saw chain and bar covered
with the chain guard (scabbard).
Properly secure your chain saw to
prevent turnover, fuel spillage and
damage to the chain saw.
To reduce the risk of
injury to your eyes never
operate your power tool
unless wearing goggles
or properly fitted protec
-
tive glasses with
adequate top and side
protection complying with
ANSI Z87 "+" (or your
applicable national stand
-
ard). If there is a risk of
injury to your face, STIHL
recommends that you
also wear a face shield or
face screen over your
goggles or protective
glasses.
Wear an approved safety
hard hat to reduce the
risk of injury to your head.
Chain saw noise may
damage your hearing.
Wear sound barriers (ear
plugs or ear mufflers) to
help protect your hearing.
Continual and regular
users should have their
hearing checked
regularly.
